Title: Vibration-proof optical system
Inventor: KINO YOSHIKI
IPC: G03B5/00
Filed: 1990-06-07
Abstract: PURPOSE:To consume no extra electric power when the vibration-proof optical system is horizontal and to prevent mechanical play effect by providing the mechanism of a variable vertical angle prism with an elastic member and applying a force in an opposite direction from a direction where the influence of its weight is exerted. CONSTITUTION:A spring 8 which is provided at the lower end of the variable vertical angle prism 1 and prevents its weight deformation serves to cancel the weight deformation of the variable vertical angle prism 1 due to oil with its tensile force. When a video camera 2 is held horizontally, the variable vertical angle prism 1 is held through the operation of the spring 8 without the influence of the gravitation, so driving correcting operration which uses a position sensor 6 and a control circuit 7 is not necessary. Consequently, two parallel flat plates which constitute the variable vertical angle prism 1 are held parallel at the time of horizontal photography which is the most standard usage, so no extra electric power is used, electric power is saved, and the power source is reducible in size.

IPC: B41J31/16
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent printing from becoming thin by forming V-shaped channels by sawtooth projections in the peripheral direction on the outer peripheral face and providing a channel being a capillary channel with a width being narrower than the max. wide part of the V-shaped channel each on the top part of the projection and the bottom part of the V-shaped channel. SOLUTION: An ink transferring rotational body 6 is formed of V-shaped channels 11b by the sawtooth-like formed projections 11a in the peripheral direction on the outer peripheral face and capillary channels 10 are respectively formed on the top part of the projection 11a and the bottom part of the V-shaped channel 11b. The ink transferring rotational body 6 are arranged between an ink supplementing device and an ink ribbon to feed ink to the ink ribbon being placed between a driving roller and the ink transferring rotational body 6.  In this instance, not only ink is stored in the V-shaped channel 11b but also the capillary channel 11 on the top part of the projection 11a sucks ink in the ink supplementing device and the capillary channel 11 on the bottom part of the V-shaped channel 11b sucks ink in the V-shaped channel 11b and as the result, as ink is stored in each V-shaped channel, the amt. of ink which can be stored on the ink transferring rotational body 6 can be increased.

Title: Data communication device
Inventor: TAKEHARA KIYOTAKA
IPC: H04L5/14
Filed: 1982-08-31
Abstract: PURPOSE:To set automatically a receiving Baud rate without recognizing a transmission Baud rate, by transmitting first a prescribed code signal from a transitter, discriminating the said code signal as the transmission Baud rate at the receiving side, and making the Baud rate of a signal processing circuit coincident with the code signal. CONSTITUTION:The prescribed code signal is transmitted as the 1st transmission signal, and a receiver 2 reads the signal Vc with a clock CL1 in 9,600 Baud into a shift register 11. The signal Vc is inputted repetitively to a receiving terminal RxD of a USART13, and clocks CL1, CL2, CL3... are switched sequentially at each input of signals Vc', Vc''.... When the transmission Baud rate is 4,800Baud, even if the signal Vc' is reproduced at the USART13 with the clock CL1 in 9,600 Baud, since the signal is different from the prescribed code signal, a CPU15 discriminates it as the dissidence in the Baud rate and switches the clock into the next clock CL2. Since the Baud rate is coincident in this case, the prescribed code signal is reproduced from a code reproducing section 12 so as to confirm the coincidence of the Baud rate. The succeeding signal processing is performed by fixing the clock of the USART13 to the CL2.
